I-75 through downtown Dayton, OH was originally an over-reach... both politically and socio-economically... or in other words, a MESS!!!

Elevated throughout the downtown area, it was plagued with multiple overpass bridges and a serpentine route. Add to that, it had multiple ramps that required overlaps of exiting AND merging traffic and odd entries and exits from the left hand lanes!

Finally, a few years ago, almost all of the roadway was completely rebuilt (took longer than the original) with an elimination of many ramps (only one super ramp to downtown) and encased earthen berms replacing many bridges (safer in winter, using less earth than traditional berms and no mowing).

This is a pic of a "tunnel" roof being placed at a spur underpass. Once completed, the roof was covered with earth and the new 6+ lane roadway. This eliminated a bridge that originally spanned both the spur, mainline and surface street.

About TrainBoard

The TrainBoard discussion forum is one of the Internet's oldest railfan, railroad and model railroad-related websites; online continuously since March 2000.

RailImages was started as a separate site in the early-2000s, before image-hosting was common on the Internet. Although online image and video hosting is
commonplace now, we still host over 100,000 railroad and model railroad-related images, and the count grows daily. RailImages is now integrated with TrainBoard,
and both domain names access the site equally.

SpecialRuns is a new project, and it is growing. We hope to offer a number of model railroad special runs in the near future.
